I found this article really interesting. www.bbc.co.uk/news/uk-57419041
There seems to have been a lot of work done on understanding genetic, psychological and societal causes of obesity in the last few years.
Some bits i found interesting.
-"It also says "Dr Abd Tahrani, a senior lecturer in obesity medicine at the University of Birmingham, says there are a lot of people who are "biologically pre-designed to conserve energy", which is stored as fat. He explains that signals from the hypothalamus - the part of the brain that controls appetite - bombard the person with feelings of hunger and a desire to eat, that are almost impossible to fight.
So even if the person successfully loses several stone by dieting, their body remembers its baseline weight and strives to return to it."
-There also needs to be a big change in the understanding of treatment, according to Mr Somers. Too many weight management programmes for those living with obesity begin with "moving more and eating less", which in reality is a prevention for obesity, not a cure.
"The number of people I've encountered in my 30-year career who've been able to go from morbid obesity, to normal weight, and sustain it by dieting alone - well I don't think I've ever met one. It's so hard to do."
-For many scientists and doctors who have developed a deep understanding of obesity, the condition is a complex illness driven by a combination of factors. To blame someone for suffering with that illness flies in the face of the scientific evidence, they say.
"If blame worked," says Dr Abd Tahrani, "we would have a very thin society by now. Everybody who has obesity has been blamed an endless amount of times, either by their doctors, by their neighbours or their family, or wider society. It's not working, please stop it.
